sunxi: Backport patches needed for A64

This backports multiple patches from kernel 4.10 which are adding
missing support for the A64 and the pine64 board. These are the device
tree files, the pinctlk and the clock driver.

+Subject: pinctrl: sunxi: Don't enforce bias disable (for now)
+
+Commit 07fe64ba213f ("pinctrl: sunxi: Handle bias disable") actually
+enforced enforced the disabling of the pull up/down resistors instead of
+ignoring it like it was done before.
+
+This was part of a wider rework to switch to the generic pinconf bindings,
+and was meant to be merged together with DT patches that were switching to
+it, and removing what was considered default values by both the binding and
+the boards. This included no bias on a pin.
+
+However, those DT patches were delayed to 4.11, which would be fine only
+for a significant number boards having the bias setup wrong, which in turns
+break the MMC on those boards (and possibly other devices too).
+
+In order to avoid conflicts as much as possible, bring back the old
+behaviour for 4.10, and we'll revert that commit once all the DT bits will
+have landed.
